World of Weeds: Kochia
This is the second article in the “World of Weeds” series. Kochia, also known as tumbleweed, is native to Europe and Asia and was introduced from Europe as an ornamental in the mid- to late- 1800s. It is well adapted to the Great Plains. Read more about this weed and why management is so important to Kansas farmers.
Pre-plant herbicide applications for kochia control
Now is the time to finalize plans for kochia control. Major flushes of kochia emerge in late February and continue through early April, resulting in dense populations that make adequate herbicide coverage difficult. It is important to apply pre-emergence herbicides in late winter or early spring to control this weed before it emerges.
Pre-plant herbicide applications for kochia control
Now is the time to finalize plans for kochia control. Recent research suggests that kochia can begin emerging in early February with most kochia emerging by early April. This article will be the first in a series discussing specific options for various cropping systems.
Late winter kochia control in fields going to corn or grain sorghum
Last week, we shared some general information about applying pre-emergence herbicides for kochia control. In this article, the focus is on specific recommendations for fields going to corn or grain sorghum this growing season.
Late winter kochia control in fields going to soybeans, sunflowers, and wheat
This is the third and final article in a series discussing pre-emergence herbicides for kochia control. For this article, we cover recommendations specific to fields that will be planted to soybean or sunflower this spring and wheat in the fall.
Considerations for weed control following wheat harvest
Post-harvest weed control in wheat stubble is very important to conserve soil moisture and prevent weeds from going to seed and adding to the weed seedbank. Weeds can grow quickly once the wheat canopy is removed.

Control of later-emerging kochia in wheat or wheat stubble
Getting kochia under control in any cropping system that includes wheat begins with the wheat crop during the spring, and shortly after wheat harvest. This is not always easy, even if early spring herbicide applications for kochia control were made. While a majority of kochia emerges early in the spring, emergence can extend over a period of weeks or months. A herbicide applied early in the spring will need to have residual activity to be effective on later-emerging kochia.
Pre-plant herbicide applications for kochia control
Kochia can begin emerging in early February with most kochia emerging by early April. Kochia seedlings emerge in dense populations that make adequate herbicide coverage difficult. It is important to apply pre-emergence herbicides in late winter or early spring to control this weed before it emerges.

Control annual weeds with fall-applied herbicides ahead of corn and sorghum
With row crop harvest well underway, it is time to start planning fall herbicide applications. Herbicide applications in late October through November can improve control of difficult winter annual weeds. Fall weed control is associated with warmer soils and easier planting in the spring. However, fall-applied herbicides may limit your crop options in the spring.

Preplant herbicide applications for kochia control
Now is the time to finalize plans for kochia control. In western Kansas, kochia is among the first summer annual weed to emerge in the spring. In fact, emerged kochia has been confirmed in fallow plots near Garden City in the first week of February this year. Good control of the first dense flush of kochia is essential for obtaining a good yield.
Late winter kochia control in fields going to corn or grain sorghum
Last week, we shared information about pre-emergence herbicides for kochia control. This week, we focused on specific options for fields going to corn or grain sorghum this growing season. It is critical to start the growing season with clean fields.
Late winter kochia control in fields going to soybeans, sunflowers, and wheat
This is the third and final article discussing pre-emergence herbicides for kochia control. This week, we will discuss recommendations specific to fields planted to soybeans or sunflower this spring and wheat in the fall.
Control of late-emerging kochia in wheat or wheat stubble
Getting kochia under control in any cropping system that includes wheat requires control in the wheat crop during the spring and shortly after wheat harvest. This is not always easy, even if early spring herbicide applications for kochia control were made. This article discusses options for controlling late-emerged kochia in wheat.
